Hi

I'm wondering if there's any books out there on 6max NL Holdem that are still viable these days. I have a pretty good basic understanding of the game, so I'm not looking for really basic stuff.

To me it feels like books are completely outdated and videos/HH discussions are the way to go nowadays. But maybe I'm wrong? All I know is that a good book would be a very welcome change after watching videos and reading topics all the time.
